A grocery chain here (Kansas, so I assume most of the US) offers their full store online with free delivery ($100 minimum). Our weekly trips have been replaced by a few minutes on the laptop. The best part for me is that the orders are tracked and I can just re-order what I bought last week or make slight modifications.
No robots yet but I hope that's not far off.
Honestly I feel almost guilty when they roll up to the deliver the groceries.
